The Keysight 8505A / 8503A is a high RF network analyzer operating over the 500 kHz to 1.3 GHz frequency range. It accurately and easily measures complex impedance, transfer functions and group delay of coaxial components and semiconductors.

A completely integrated system including both the sweep oscillator and receiver

Companion instruments include the Keysight 11850A Three Way Power Splitter for high resolution transmission comparison measurements, the 8502A Transmission/Reflection Bridge for simultaneous transmission and reflection measurements, and the 8503A S-parameter Test Set for complete characterization of two port devices in a single test set-up
